I am travelling on business right now so I can't look at the calipers but yesterday I did take a look and there were four bleeders on each caliper. One on each end of each side. No crossover pipe and I didn't see any other threaded inlet between the pistons. I have the billet Dynalite II calipers. I have assumed that I will have to remove one (or possibly two) of the bleeders and install the inlet line there. Roscoe's caliper appears to not be a billet model, quite different from mine.
I now wonder if I was half asleep
when looking at the calipers. I will get back to you tomorrow evening when back at home.
